On arriving home, I looked anxiously at the message-book, and was relieved to find that there were no further visits to be made. Having made up a mixture for Mr. Graves and handed it to the coachman, I raked the ashes of the surgery fire together and sat down to smoke a final pipe while I reflected once more on the singular and suspicious case in which I had become involved. But fatigue soon put an end to my meditations; and having come to the conclusion that the circumstances demanded a further consultation with Thorndyke, I turned down the gas to a microscopic blue spark and betook myself to bed.
